Losing the Malevolent cuirass by being killed in the Wilderness will result in a percentage of the original malevolent energy being dropped on death, equal to how degraded it was, rounded down. For example, if the cuirass had 100% of its charges remaining, 42 malevolent energy would be dropped on death, and if it had 52% of its charges remaining, 21 would be dropped. This can be used to refund most of the cost of the cuirass, although the reinforcing plates are not returned.

There was a bug/change causing 1 energy to be returned, regardless of percentage, when killed in the Wilderness. This was fixed.

This armour can be dyed using barrows, shadow or third age dye to make the armour into the barrows, shadow or third age variants, respectively. This makes the armour untradeable, but it will not crumble to dust when it fully degrades; rather, it can be repaired for a monetary cost.
